If I look at the way Redhat created a similar on a working system, I get
the following information for the lv's created:

# lvscan
  ACTIVE            '/dev/VolGroup02/LogVol00' [3.56 GB] inherit
  ACTIVE            '/dev/VolGroup02/LogVol01' [320.00 MB] inherit

Based on the above information, would you say that it is a reasonable to
say that on the broken drive, the first lv was LogVol00, used for data and
the second lv would have been LogVol01, used for swap.  Could I, like you
suggested create a logical volume for the total size and perhaps get my
data back (since the swap is at the end of it all?)

Is creating a logical volume with lvcreate also only adjusting the
information about the lvm and not actually touching the data, which means
I can safely experiment, trying to change the lv's until I find the
correct size? (I hope my questions make sense)


Random Thought:
If you are smart enough to know that you're not smart enough to be an
Engineer, then you're in Business.
